The reason is that every other major country subsidises chip manufacture in some way or another, making the US undesirable. Last I read, China has subsidised fabs by upwards of 70%. Europe has followed suit with their new chip funding legislation. It doesn't make financial sense for a global company to fork out multiple billions if they can do cheaper elsewhere, ie, Intel's new fab in Germany.
